we won't see any "Apocalypse" in our lifetime. Our lifetime is no more significant than any other. And every other generation imagined an "Apocalypse" in their lifetime.

They'll eventually be some asteroid that slams into us and starts everything anew. Maybe in 50 million years we'll have an intergalactic highway powered by cold fusion that was invented by some highly involved mollusk. But thinking that we'll witness that initial doom is just us projecting our own existence onto the bigger picture. As we tend to do.
